A project log for Self Clocking ROM

There are a few projects that can be implemented with a ROM and need a clock source...

Just because something works, doesn't mean it works well. It can be important to play with it and understand the limits to operation...

I grounded the remaining address lines, and started playing with values. After trying a variety of inductors and capacitors that all worked great and produced different operating frequencies I realized that an RC delay might also work just fine...

An RC delay actually worked with cleaner operation than the LC!

I was able to hit about 3MHz with a small cap and low resistor value. So the range of operation is great!

Next test is to apply it to something...
